Some thing also to check, is that they have a Hanna checker out, that reads PPB, It's an ULR phosphate reader. I have a reading of .0004ppb in my tank.

I can't remember the details exactly but I remember reading a thread were Randy Holmes Farley explains that the ULR phosphorus checker is not much more accurate than the phosphate checker.
